What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)
Samples
11 samples: 4 × C vs 4 × D vs 3 × NGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Summary (written by the submitters)
Colitis-associated colorectal cancer (CAC) is a serious complication of inflammatory bowel disease (IBD) with complex etiology involving chronic inflammation, immune dysregulation, and gut microbiota dysbiosis. Creatine, a natural nitrogenous com-pound, possesses anti-inflammatory and immunomodulatory properties, but its role in CAC remains unclear.We established an AOM/DSS-induced mouse model of CAC and supplemented mice with creatine.

We assessed the effects of creatine on colitis severity, tumor burden, and histopathology. Additionally, we investigated the impact of crea-tine on gut barrier function, macrophage polarization, and gut microbiota composi-tion.Creatine supplementation significantly alleviated DSS-induced colitis, reduced tumor burden, and delayed CAC progression in mice. Mechanistically, creatine im-proved gut barrier function by protecting tight junction proteins from degradation in-duced by the modeling stimulus,influenced macrophage polarization, and main-tained gut microbiota diversity, promoting the abundance of beneficial bacteria while reducing harmful ones.Our findings suggest that creatine supplementation may rep-resent a promising supportive therapy for IBD and CAC by modulating the gut micro-biota and immune microenvironment. Further investigation is warranted to explore the clinical potential of creatine in the management of CAC.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE293077_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1242752 and SRA study SRP573937. Searching any of these in the dataset finder brings you back here.

Study design
4 × C vs 4 × D vs 3 × N

Supports a between-group comparison across 11 samples.

How we read this: 3 replicated groups read from 11 sample titles; they account for 11 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
